“…10 The value for the anharmonicity constant, ω e x e , differs considerably from the value of Rodriguez et al (0.24 ± 0.03 cm −1 ); however, this difference could arise from the low resolution of the earlier study (∆λ = 0.15 nm). For PbI, there have been several computational chemistry studies carried out; the work of Benavides-Garcia and Balasubramanian determined the value of ω e to be 153 cm −1 , which is on the low side of the experimental value, and a D value of 20 486 cm −1 which is in good agreement with the values estimated using Equation (9) …”

“…Rodriguez et al reported an absorption and emission UV-spectroscopic study on the A, B, D, and E electronic states of PbI by photodissociation of PbI 2 . 10 They give values for the vibrational constants (ω e and ω e x e ) of the ground state and the A electronic state. A number of computational chemistry studies have also been carried out on PbI.…”

Articles you may be interested inPure rotational spectra of the ground electronic states of lead monoiodide and tin monoiodide have been measured using a chirped pulsed Fourier transform microwave spectrometer over the 7-18.5 GHz region for the first time. Each of PbI and SnI has a X 2 Π 1/2 ground electronic state and may have a hyperfine structure that aids the determination of the electron electric dipole moment. For each species, pure rotational transitions of a number of different isotopologues and their excited vibrational states have been assigned and fitted. A multi-isotopologue Dunham-type analysis was carried out on both species producing values for Y 01 , Y 02 , Y 11 , and Y 21 , along with Λ-doubling constants, magnetic hyperfine constants and nuclear quadrupole coupling constants. The Born-Oppenheimer breakdown parameters for Pb have been evaluated and the parameter rationalized in terms of finite nuclear field effects. Analysis of the bond lengths and hyperfine interaction indicates that the bonding in both PbI and SnI is ionic in nature. Equilibrium bond lengths have been evaluated for both species.

“…The microwave spectrum of PbI was recorded recently in our laboratories and presented together with derived geometrical parameters of the molecule in 2014 [4]. In the present work, the extensive results presented in [5] are combined with results obtained by other workers for different wavelength ranges [6][7][8][9][10][11] and used for the potential energy function fitting described in Section 3.2.2. The microwave spectrum of InI has been explored by several previous works [12,13] with the most recent study having been performed in 2006 [14].…”

Pure rotational spectra of PbI and InI are interpreted to yield a full analytic potential energy function for each molecule. Rotational spectra for PbI have been retrieved from literature sources to perform the analysis. Rotational transition frequencies for excited vibrational states of InI (0 < v < 11) are measured during this work. Ignoring hyperfine splittings, B v and D v values are used to generate a set of "synthetic" pure R(0) transitions for each vibrational level. These are then fitted to an "Expanded Morse Oscillator" (EMO) potential using the direct-potential-fit program, DPOTFIT. The well-depth parameter, D e , is fixed at a literature value, while values of the equilibrium distance r e and EMO exponent-coefficient expansion (potential-shape) parameters are determined from the fits. Comparison with potential functions determined after including older mid-IR and visible electronic transition data shows that our analysis of the pure microwave data alone yields potential energy functions that accurately predict (to better than 1%) the overtone vibrational energies far beyond the range spanned by the levels for which the microwave data is available.
